Notebook recording sound quality

There is a big difference. First of all, talk about the recording pen.

The framework of digital recording pen is roughly as follows

Analog signal (sound) acquisition → signal conversion processing → information storage → playback output.

Regardless of the price, a digital recording pen must have four hardware.

Recording generally goes through these four steps.

Let's compare the first two of the four steps mentioned above.

Analog signal acquisition: The hardware of recording pen is absolutely inferior to that of condenser microphone.

Although Sony's high-end recording pen has a built-in microphone, it is not a capacitor, let alone a moving iron or a moving coil. Electronic vacuum tube, but ordinary electrostatic microphone. The reason is very simple. The above-mentioned centralized common radio head is sensitive, not suitable for mobile use and easy to be destroyed, so we can only choose electrostatic microphone head.

You have a condenser microphone. In this respect, the recording pen is definitely not as good as the microphone, but the quality of the microphone that comes with the notebook is similar to that of the high-end recording pen (the model of 2300 can't be compared).

Signal conversion and processing: this is not easy to compare. Let me give you an example. The processing method of Sony PCM-D50 is PCM processing, and now many chip schemes of cheap sound cards (such as X-Fi chips) also adopt this method. Sony PCM-D50 is priced at 2800, which is the top recording pen. Ordinary sound cards 4 and 500 are enough. Why don't you think about it? Can 2 and 300 recorders use PCM?

So I can tell you now that the recording principle of 2 and 300 recorders is basically the same as that of laptops (no external equipment is needed), and the sound quality is also different. The difference lies in signal conversion and processing, because I don't know the processing scheme of this kind of recording pen and integrated sound card, so I can't tell who has good sound quality.

But notebook+external sound card+condenser microphone will have a qualitative leap in sound quality, which will be very different from the above sound quality, which you have to believe. (Pro-test certificate)

Hello, I have solved your problem, I hope to adopt it, thank you!
